What is your proposal to ‘fix’ this ‘problem’?

This is where the actual issue is I think. The usual solutions proposed are to increase taxes on the 10%, and increase spending much more than that, and inflate the money supply. A lot of people see all of this as the exact mechanism which transfers wealth to the 0.01% at the expense of everybody else.

Has there ever been a centrally-planned economic policy implementation that actually reversed concentration of wealth and power?
